RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTP_HOST} ^example\.com$ [NC]

If you are using nginx, then add this line to nginx config:

server {
  listen 80;
  server_name yourdomain.com;
  rewrite ^/(.*) http://www.yourdomain.com/$1 permanent;
}
